Kublai Khan is the grandchild of Genghis Khan?

The story behind the answer

True—Kublai Khan was Genghis Khan’s grandson. He was the fourth son of Tolui (Genghis’s youngest son) and Sorghaghtani Beki, placing him in the direct line of succession within the Mongol imperial family. After his brother Möngke died, Kublai claimed the title of Great Khan and eventually founded the Yuan dynasty in China in 1271, completing the conquest of the Song by 1279.

Kublai shifted Mongol power toward China, ruling from Khanbaliq (Dadu, modern Beijing), and his court famously hosted the Venetian traveler Marco Polo. Memory tip: think “Genghis → Tolui → Kublai”—three steps from founder to emperor—linking the Mongol Empire’s origin to its transformation into a Chinese dynasty.
